More hype than harvest – the reality of new GM crops

At present, only three genet­i­cal­ly mod­i­fied crops devel­oped with new tech­niques such as CRISPR/Cas are on the mar­ket world­wide. That’s the key find­ing of the New GMOs Mar­ket Report, pub­lished by the Euro­pean Non-GMO Indus­try Asso­ci­a­tion (ENGA) and the US-based Non-GMO Project.

Overregulation in the EU?

Sup­port­ers of the pro­posed dereg­u­la­tion of genet­i­cal­ly mod­i­fied (GM) plants often claim that the EU’s strict rules are sti­fling the mar­ket intro­duc­tion of new GMOs engi­neered with new GM tech­niques (NGTs). But even in coun­tries with lit­tle to no reg­u­la­to­ry hur­dles, the roll­out of these new crops has been slug­gish at best.

New GM tech­niques — in the EU also referred to as new genom­ic tech­niques (NGTs) — include tech­nolo­gies devel­oped since 2001, such as gene-edit­ing tools like TAL­ENs, ODM and CRISPR/Cas.

The New GMOs Mar­ket Report shows that only three NGT crops are cur­rent­ly grown com­mer­cial­ly: two in the Unit­ed States and one in Japan. The US crops are two CRISPR-edit­ed maize vari­eties engi­neered for resis­tance to cer­tain insects and the her­bi­cide glu­fos­i­nate (which is not allowed in the EU). Because these plants con­tain “for­eign DNA,” they would not fall under the scope of the EU’s pro­posed dereg­u­la­tion.

In Japan, a CRISPR-mod­i­fied toma­to is on the mar­ket and pro­mot­ed for its ele­vat­ed GABA con­tent, which is said to low­er blood pres­sure. Whether this toma­to would qual­i­fy as “con­ven­tion­al-like” remains unclear.

Two oth­er gene-edit­ed crops that once reached the mar­ket have already been with­drawn due to lack of suc­cess: a her­bi­cide-tol­er­ant ODM oilseed rape devel­oped by Cibus and a TAL­ENs-mod­i­fied soy­bean with altered oil con­tent from the com­pa­ny Calyxt. Nei­ther crop is being cul­ti­vat­ed today. Cibus has acquired Calyxt — and is cur­rent­ly fac­ing inves­ti­ga­tions by sev­er­al US law firms over alle­ga­tions that it mis­led investors.

Hype meets reality

The Euro­pean Com­mis­sion and oth­ers often tout the promis­es of new GM tech­niques. They argue that these meth­ods make it faster and eas­i­er to achieve breed­ing goals, com­pared to tra­di­tion­al plant breed­ing. But what has actu­al­ly been achieved? Which prod­ucts are on the mar­ket? Which ones are still in devel­op­ment? So far, such infor­ma­tion remains sparse, hard to access, and often dif­fi­cult to ver­i­fy.

Accord­ing to the new report, 49 NGT crops are cur­rent­ly in devel­op­ment globally—most of them in the US and Chi­na. It is hard to tell how many will tru­ly reach the mar­ket. Many of the NGT plants approved in the US are not actu­al­ly being cul­ti­vat­ed. In Chi­na, not a sin­gle NGT crop is being grown com­mer­cial­ly at this time.

Traits like drought or dis­ease resis­tance, often cit­ed as key ben­e­fits of new GM tech­niques, remain rare in prac­tice. Only a hand­ful of maize vari­eties, one soy­bean, and one wheat line are cur­rent­ly being devel­oped for such prop­er­ties.
